EDGE TRIM GAUGE Fild Jan. 6, 1959 Patented Mar. 12, 1940 1 Claim.

This invention relates to setting straight edges for marking and cutting. v

This invention has utility when incorporated in locating for marking or trimming the edges of sheet stock, as wall board or wall paper,-'more'es pecially as to removing the 'selvage and wall paper strips which have been pasted and folded to have thepas'te inside. 7

Referring to the drawing:

Fig. 1 is a plan view of an embodiment of the invention in connection with a straight edge and trimmer for wall paper selvage;

Fig. 2 is --a section on the line IIII, Fig. 1,

showing the device with parts broken away;

Fig. 3 is a section on the line III-III, Fig. 2, showing thedevice in mounted position at the track; v I I Fig. 4 is a view of the device from the left of Fig. 2; and I Fig. 5 'is a view 'of the trimmer having the device in conjunction therewith.

Paper as in strips may be coated with paste or adhesive on the back side or upper surface as the paper is placed with the decorated surface or face down on table I. As so pasted, the paper 2 is folded on itself inwardly from its overall length to have its ends 3 abut and thus expose the printed or decorated surfaces throughout and have the paste-carrying surface concealed. In such folding with the pasted portion on itself to leave the printed side exposed, decoration 4 may com to margin 5 in determining selvage distance at one side and a diiferent margin 6 for determining selvage on the opposite side. In the set-up hereunder, marker plate or strip 1 is shown as having effective straight edge 8 and adjacent thereto countersink 9 with overhang l0 forming a track. In this track as a guide may run trimmer ll having track coacting means l2 and cutter disk It directed by the track coacting means 2 to have this cutting disk l3 travel at the straight edge 8 in trimming the paper 2.

Facility in carrying out this operation is effected hereunder by accessory block M, shown as having transversely thereof pair of parallel guide ways or parts IS, in each of Which is rod It or 13' as a gauge finger having oiTset terminus l8, These rods may be relatively short for taking care of a set of operations which may run from inch for trimming off the narrower side and up to 1 inch for trimming off the wider side' of the paper or strip. While for greater clearance, say up to ,7 inches or more, longer rod may be used. In either instance the rod [6, ll, is readily slidable in the guide-way l5 transversely or the direction or the block l4 as'resun'g on the plate l. I At the adjusted. position away from the block 'i l' for the terminal finger I8, such may be locked by a'set' screw I9. In this locking, the terminal finger 18 may beat the edge of the paper' 2.

Such location may thus determine a line of travel for the cutter l3 atthe clearance from the edge of the paper as directed by the straight edge 8, the position of the straight edge having been determined by the "locationof the pointer Hi. The straight edge is thus placed tovdirect the operation of the cutter for. removal of a strip at the edge of the wallpaper, which wall paper has been folded to have its pasted side inside and the printed side exposed. This position. may be adopted for wider gauge as placed by the rod 56, for locating the trimmer line of cut to be taken oil a strip of stock; For the narrower or other selvage" edge'o'f said, stock, the rod 11 may be positioned and held so adjusted by the setscrew l9. Notwithstanding there has been located two positions for the ofisets or fingers, it is in order to use one of these accessories atthepaper edge for oneof the cuts. For such use, the trimmer ll may travel freely along and even thrust or push the guide finger to be clear ofinterference of the trimmer operation. This iseffected without disturbing the line of set for saidfinger in its clearance as to the straight edgeyand is accordingly for the full dimension or range for the paper to be cut. Similar'handling may be had in replacing the straight edge in operation accord-- ing to the other gauge. It 'is to be noted that in this disclosure there is available at all times full freedom for trimmer travel as to the straight edge 8 of the plate 1.

' In practice, it may be desirable to supplement I the accessory by installing or adapting a pair thereof to the track.

1 2| may be adjusted for nicety of undergripping due to'slot 23 and clamping nut 24 as to bolt 25, also mounting plate 20 if separate.

In the set-up hereunder, it is thus seen that the plate 1 may be placed on the folded pasted paper 2 with an accessory block I4 adjacent each end of the paper. As so positioned and with the trimmer therebetween, such trimmer II may be operated along the track for the full length of the paper independently of any special handling .of either gauge device or locator as such may be shoved clear of the paper as the trimmer strikes such. This progressing of the accessory by the trimmer can serve to progress the offset I8 as an indicator from the initially set position to be noted by the operator oflthe trimmer as to whether such is maintaining the desired relationship for the clearance along the paper.

These locators or gauge means may be shoved clear of the plate I as to its track by the trimmer or slid clear thereof, say for other use of the plate. the plate from the table say to hang or be suspended, the locators may be left in position with or without the trimmer at the track. "The plate is free as normally for locating the straight edge and the plural fingers mean that there may be one adjustment for one side of the paper strip and a different adjustment for the opposite side as determined say for a batch of paper or of room lengths for cutting. With this assembly for the pair of fingers in each block, there is available to the worker a speed of operation in the trimming with accuracy in determining paper edges for butt or wire edge or other type of finishing as may be in order.

The block I4 with its pair of guides and limiting of such to complementary track coacting means renders this device progressively coactive in practice. Instead of an individual accessory to such purpose there may be at a side of the cutter clear of the trimming wheel an extension 26 from the body of the, cutter II,' whereby the cutter coaction with the track serves as the directing means for this gauge. Under such cir- However, when it is only desired to'shift cumstances, the cutter II (Fig. is herein shown with the extension block 26 serving as the block I4, wherein the set screws I9 adjust the respective rods I6, IT, for such to locate their offset termini I8 differently as to the opposite edges of the paper. Thus the location at one end for the paper strip and progressing of the cutter therealong at the adjusted position may leave the observer free to check the oifsets I8 as to their proper clearance position travel line as the cutter is operated or with the cutter idle in the trimmer II.

Herein the block is a unit of small dimension, readily placed in the operators kit or pocket, and available for accurate dimension use in the Widerange in practice. Accuracy and speed in adjustment may be effected, whether the set screws be set by hand or screw driver. The general feature is that the block is of coacting features for definitely locating with the track for free travel therealong.

What is claimed and it is desired to secure by United States Letters Patent is:

A marker plate having a straight edge and a countersunk guide forming an overhanging track parallel to said straight edge, a runner embodying a block spanning between the edge and guide, there being complementary way means fixed with the block directing the block for freely traveling as directed by the guide and coacting with the straight edge against otherwise shifting as to the guide, there being port means through the block clear of the plate, pointer means in and protruding from the port means to overhang in spaced relation from the straight edge, and set screw means in the block transversely of the port means for anchoring the pointer means in adjusted position as to the block.
